Hi All, I'm inexperienced in the Lidar space and I am looking for a camera type being able to scan, process and display in real-time at a range of about 10-15m with a resolution of about +/-50mm. Ideally the ability to geo locate anomalies above a certain threshold. The application would be on a machine with travelling speeds of 5-15kph. What is a good starting point for camera and software?

In cases where the scanning environment is large open spaces (not like interior BIM scans or close-range utility scans). Instead of moving a scanner over and over that only has a range of 70-100 meters max, would it be possible to scan with larger format scanner with a huge range?

I'm newbish and don't really understand the science behind why lidar PC quality diminishes as it's range gets closer to (or beyond) its recommended limit.

I use to run a AV lab which got shut down. I have bunch of Livox HAP and Horizon lidars for sale. HAP are like new and hardly use where as Horizon is used well. DM me for details.

I am trying to run my lidar mid-360 on my livox veiwer and the motors inside are runnin how ever the lidar does not appear in the veiwer… keep in mind i did not use the function cable and i dont know what did i do wrong

Hey there, I’ve shared this settlement before, but here’s an important update: Velodyne is accepting late claims, so you can still file for payment even if you missed the original deadline.

For those who don't remember: during COVID times, Velodyne announced in a press release that its founder and CMO were under investigation and removed from their positions. The reason? Allegations of showing a "lack of respect, honesty, and integrity" toward the board and other key figures in the company.

Unsurprisingly, this news caused $VLDR shares to drop, and investors responded by filing a lawsuit.

The good news? Velodyne recently agreed to pay a $27.5M settlement to investors over this. So if you were impacted, you can file a claim, even if you’re late.

Hope this helps!

I've got an LAS point cloud generated by photogrammetry. The points are colored the same as the objects photographed but not classified. The ground is not a uniform color (grass, asphalt, gravel, etc) What are good options for automated extraction of the ground surface by filtering out structures, trees, cars, etc?

We're having an issue in spatial Explorer when activating the Riegl it says LASER_SWITCH_IS_OFF. Any ideas how to solve this issue would be greatly appreciated.

Thanks,

I'm working on a project where I hope to mount a LIDAR unit of some sort to the front of a bicycle, pointed down at the pavement surface, so that I can log data about how deep and wide cracks and potholes are on paved bike paths. But I have no idea where to start.

Do I need 2D or 3D LIDAR for this? Are there hobbyist LIDAR units that I could connect to a Raspberry Pi or something portable to log the data?

I guess the accuracy I need is somewhere around 2 mm? Ideally I would like to capture a perpendicular width of at least 30 cm, and depth up to 15 cm. I guess parallel width would be unlimited since that's the direction the bike would be traveling.

Budget under $10,000 if possible? Ideally much cheaper if I can DIY it to some degree without much hassle.

I have no idea what I should even be searching for. Links and terminology are much appreciated!

Hi there everyone! I am posting this in the hopes of finding someone that has the computer skills to use the Maryland.gov LiDAR Download Tool and could help me with getting ahold of LiDAR scans of an area known as Wetipquin Neck. My ancestor, Julian Mezick, was the first colonial landowner of this area, around 1675. There are thought to be a couple of cemeteries in this area. I am hoping to pinpoint them using the LiDAR scans, and get one step closer to finding the resting place of his remains.

If anyone could download the scans of this area, I would really appreciate it. I can't figure the website out, and I'm pretty tech savvy. Alternatively, if anyone has any other leads on ways that I could access LiDAR information of this area?

Sort of curious about doing some atmospheric research, firing a laser across a valley at an inaccessible rock face a ways away. Are there any hobbyist-grade laser rangefinders that can work out to like, hundreds of meters? It'd be nice if it could do multiple returns, but I could make first or last-return work ok too. Infrared is probably the best.

Is there a database that shows which current cars have a 360° lidar sensor build in?

Hi everyone, I have been working in a proyect about transform a cloud of points in a solid object but in the way i found a lot issues like an object with a bad structure, right now i have been reading papers about neural architecture but in windows I always find erros, Does anyone know how to process this data?

I would appreciate anyone who could help me. Thanks.

Long story short, I have to become up to speed at work with LiDAR and camera fusion, yesterday (figure of speech). What I need for now is a LiDAR under $2500 (fixed asset limit) and a camera. How is the https://www.livoxtech.com/mid-40-and-mid-100 mid-40 or mid-70 for a LiDAR? The LiDAR and the camera will be static, analyzing the moving objects of a scene. I just need those for testing/prototyping indoors and getting up to speed with software.

If you can suggest, an open-source software, that would be great too.

I am asking to get the most common LiDAR/camera/software combination, so I don't land on something exotic accidentally.

Hi, I'm new to this subreddit, so I hope it's okay if I share my company's LiDAR application development experience. Maybe this will be useful to someone working on such projects.

You can find the article here.

I have a question. I am planning to carry out a mission in a high-density urban construction site, where there are ongoing constructions (e.g., cafés, buildings) and a lot of movement from people and vehicles. Is it possible to use SLAM (Simultaneous Localization and Mapping) for this purpose? The goal is to generate a 2D map and reconstruct it into a point cloud. Could you please suggest a possible approach for this task?

Hello Everyone,

I am learning las data classification using Terrascan. It is easy to identify objects such as powerlines by creating profile and classify them but I am facing difficulty identifying difference between small hill and vegetation. Is there any material or workflow by which I can differentiate it better. ?

Thank you.

I'm exploring ways to better weed out vegetation. I can't seem to find a software that says it'll remove points based off normal values. Is anyone aware processing/post processing software that will do that. I get the reflectivity, intensity, color methods etc..., but at times I think i can get better true ground data based off filtering the normals. Just want to know before I commit to a new program. DJI terra/Pix4d and Recap and Civil3d was fine for asbuilts and progress tracking, but we're moving onto flying sites before breaking ground.

I’m struggling to use this sensor, as the SDK is Linux based and I’m very unfamiliar with Linux/Ubuntu.

There is a Unilidar software that you can use on windows, but it only shows the LiDAR data imagery. There’s no way the program enables you to extract the Point Cloud Data (at least from what I can tell). Has anyone figured out if you can extract the data from this sensor strictly on windows?

I’ve been spending the last 3 days trying to use WSL2 as well as Linux dual booting and it’s been a struggle. All I need is to record the data and save as a PCD file so I can feed it into Matlab for further processing.

Below is a link to the sensor on YouTube: https://m.youtube.com/watch?v=2wJatVbJfns

Any help you can offer would be greatly appreciated.

Hi, anyone has a recommendation of LiDAR Scanner app that is a one off payment?

I like how PolyCam works, and it’s great, but the subscription model really puts me off.

I own the hardware but I can’t use it unless I paid a £120 a year? That’s sounds like robbery to me.

To be honest Apple should provide their own LiDAR Scanner app. Do they have, or am I just ignorant to not known about it?

TIA!

Hello! I'm new here. I've been working on a retro futuristic universe that is inspired by 1930s-1950s era sci fi. Although I want it to have the feel and flavor or those eras, I still want to incorporate quasi-realistic technology to keep the science relatively "hard", even if it's a bit anachronistic (lidar wasn't really invented until the 60s, right? My research could be wrong).

Is anyone here familiar with colidar? Evidently it's similar to lidar, but it's what they called it back in the day. Since the aesthetic of my stories is retro, would it make sense to use the term colidar instead of just lidar? I love the old terms from that era of science (everything was gonna be atomic!) and think it sounds "cooler" and "more retro" than simple lidar.

Hope this makes sense as a question, and thanks for your time.

Hello people, I am new to lidar and algorithms. I am having a project to make Agile x scout mini to autonomously drive. I need some help regarding the RPlidar s1 and implementing slam out of it. I am using ris noetic and I am finding it difficult to get the offline and online slam can anyone helpe with what exactly I need to do.

I am looking for a gps module compatible with Velodyne VLP-16 board, I need to equip it in my custom UAV (Ardupilot). Or if there is a way to feed gps data from my flight controller as well as IMU data.

Newb question here. Is point density on stationary scanners affected by distance the same way airborne lidar is affected by flying altitude, or is the range not long enough to begin with to be a factor on density? If I were to position a scanner to capture a building and the scanner had a 150-meter range, would trees or other distant background objects 140 meters away capture at the same point density as the building directly in front of the scanner?

I’ve just gotten some new-ish lidar data as .laz files, I’ve used the Convert LAS tool in ArcPro and the tool runs successfully. When I import the newly created .las file it’s displaying in the middle of the Pacific Ocean rather than in Montana where it should be. I’ve tried the Define Projection tool as well as the Extract LAS tool hoping it would re-project but everything I’ve tried has ended up with the same result. Anyone have any ideas what I’m doing wrong?

Hi, what is the better CPU for LiDAR, the i9 14900K or Xeon W3-2423, our budget only allows a mid-range computer and it has to be a Dell Precision.

Description of usage: needs to be capable of analysis of LiDAR and other big datasets.  at present researchers often wait hours for things to process (4 year old Precision 7920 Tower). recent hydrology modelling on this lab computer had to run for days.
